Sanitary Sewer Overflow Due to Vandalism, Warning Signs Still Posted

Due to vandalism, sewage has overflowed directly into Mill Creek and into the Columbia River. The sewer pipe has been cleared and the pipe has been repaired. No more sewage is overflowing.

Out of an abundance of caution, signs have been placed at locations of public river access on the Oregon shore of the Columbia River, from The Dalles Riverfront Park to West Mayer Park boat launch. The signs say: “Warning - Contaminated Water - No water contact” and give phone numbers to call for information.  These signs will remain in place at least until Thursday September 29, 2022 to allow time for water quality testing. Read the full press release here.
